Abstract
Abstract
The objectives of this study is to adsorb 2, 6-dichloro phenol indophenol sodium salt using nano magnesium oxide as a nano surface. The adsorption of dyes by using the nanoparticles is a modern and effective way to remove contaminants from their solutions. The UV spectrophotometer was used to follow the dye concentrations in the water solution after mixing them with 0.1 g of MgO and different concentrations of the dye solution were used to obtain the isotherm adsorption. The application of the Langmuir and Freundlich isotherms adsorption was investigated. The isotherm estimate shows that the Freundlich model obtain better fits to the experimental equilibrium data than the Langmuir model. The effect of temperature was investigated, the best temperature was 298 K. The adsorption decreases by increasing the temperature. The values of ΔG revealed that the process of adsorption was spontaneous within the experimental conditions. The effect of the acidic function was also studied. The adsorption value changed with the changing acidic function. The results showed that nano magnesium oxide can adsorb 2, 6-dichloro phenol indophenol sodium salt efficiently.
